ARTIFICIAL-TOOTH MOUNTING.

Application filed December This invention relates to new and useful improvements in artificial tooth mountings for use in dental bridge work.

The object of the invention is to provide a mounting in the form of a yoke adapted to engage in the rear side of the tooth in such a manner as to effectively hold the tooth against displacement and to provide a metal support, which may be readily soldered or N brazed to the bridge or other connection.

A particular object of the invention is to provide lugson the mounting for engaging in notches in the tooth, whereby the tooth will become more securely fastened w in the mounting when subjected to downward pressure.

Another objec plify the mounting as we ceived therein.

A. construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is a back view of a bridge tooth, mounted in accordance with my invention,

as Fig. 2 is a side elevation of a tooth and its mounting,

Fig. 3 is a side elevation of a tooth with the mounting removed,

Fig. 4 is a similar View,

85 being in section,

Fig. 5 is a perspec ing, and

Fig. 6 is a horizontal cross-sectional view on the line 66 of Fig.2.

In the drawings the numeral 10 desi nates an artificial tooth which is suitabfy formed. On its posterior approximal portion the tooth is formed with a recess. or groove, 11 extending around its rear side and forwardly a short distance on each side to the central portion. The recess is directed inwardly toward the center of the tooth'and terminates at each end in a directed notch, or socket, 12, directed toward so the occlusal portion of the tooth as is best t of the invention is to simll as the tooth rethe mounting tive View of the mount- HETSSUEB recess is preferably of the tooth, as is 10, 1926. Serial No. 153,763..

shown in Fig. 3. v The flared toward the rear shown.

The mounting consists of a metal-yoke 13 shaped to fit in the recess 11 and having angularly projecting rounded lugs 14 at-each end, adapted to engage in the sockets 12. The yoke may be formed to fit in the recess flush with the surface of the tooth, or it may have an upwardly extending flange 15 extending over the surface of the tooth,

It will be seen that the yoke forms a and when made to snugly engage in 11, will hold the tooth against This is particularly due to d the sockets 12, whereby oce tooth will merely clamp the recess displacement.

the lugs 14; an clusal pressure on th force it into ti hter engagement with. the yoke and ofi'set displacement. A much more effective fastening will be had by use of the lugs and sockets.

when secured-1n the recess The mounting,

be brazed or soldered to of the tooth, may the bridge work, as is shown in Fig. 1, or practiced by secured in any other manner dentists. The mountin provides sufiicient metal on each side of t e tooth and in the rear, if necessary, to substantially connect it with the desired support; however, the mounting is concealed and the artificial tooth presents a natural appearance in front elevation.

Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the. scope of the appended claim.

What I claim, is:

An artificial tooth mounting includi artificial tooth having a clrcumfer recess in its posterior approximal portion extending to each side of the tooth and terminating in sockets disposed toward the occlusal portion of the tooth and having reduced entrance portions, and a mounting yoke band fitting said recess and having lugs formed with a reduced neck and interlocked in said sockets to prevent direct with drawal therefrom.

In testimony whereof I afix ROLPH L. S ":l i l ng an si 1 ature.
